Carpool Karaoke looks like a ton of fun, right? Well, if you think this, you certainly aren't the only one. But on the flip side, there are those that don't find it that much fun. Like the Foo Fighters for instance. Filming Carpool Karaoke was not the most pleasurable experience for the band.

“By hour three in dude’s car, it got less fun,” guitarist Pat Smear said, adding that, “When we stopped at Guitar Center, that felt like we were done, but it was like, ‘this is halfway.’ ”

Dave Grohl did say that the experience was a little bit uncomfortable, but he didn't hold it against James Corden. And he preferred to sing other songs, and not his own.

“Oh he definitely is [a music lover]. And he’s a very nice guy,” Grohl added. “But you know, I don’t mind singing my own songs at Glastonbury or The O2, but if I had to sing you a song right now, I’d be too embarrassed.”
